There is one very simple test that can prove it. Check handwriting, including spray-painting and see if any of them write in such a distinctive way. Today at the Shabbat women's class I've been participating in every week (for the past 34 years,) if they know of any young Jewish men who have handwriting like this or of any school that trains the students to form letters like this.

Total silence greeted my question. Our group consists mostly of grandmothers and even a great-grandmother. We all know how boys of that generation write. So, why do the Shabak keep torturing the boys instead of simply checking their handwriting, especially with spraypoint which is much more difficult to control?
